## Abstract

A battery pack includes a battery unit including rechargeable batteries, a sensing board, the sensing board configured to process status information detected from the batteries, and a harness wire, the harness wire connecting the batteries and the sensing board so that the status information can be transmitted to the sensing board.

## Claims

### Claim 1

A power storage system, comprising:
a plurality of battery packs, each battery pack including:
a plurality of rechargeable batteries,
a sensing board, the sensing board being configured to process status information detected from each of the batteries of the respective battery pack, and
a harness wire, the harness wire connecting the respective plurality of batteries and the sensing board of the respective battery pack for transmitting the status information to the sensing board of the respective battery pack;
a battery management system (BMS) for controlling the status of the battery pack; and
a power management system (PMS) for controlling overall power supply among the battery pack and peripheral devices, wherein:
the peripheral devices include a power generating system for generating power and a commercial grid,
the PMS is configured to receive power from the power generating system and the commercial grid, and
the PMS is interposed between the power generating system and the commercial grid so as to control all power passing between the power generating system and the commercial grid.

### Claim 2 (depends on 1)

The power storage system as claimed in claim 1, wherein the battery pack has integrated therein a battery unit that includes the respective batteries, the sensing board, and the harness wire.

### Claim 3 (depends on 2)
